Is possible : javascript extract value from c:forEach tag?
18,532
Just print it in JavaScript syntax instead of HTML syntax.
<script>
var data = {
<c:forEach items="${cTagBean.tagList}" var="ctag" varStatus="loop">
'${ctag.name}': ${ctag.age}${!loop.last ? ',' : ''}
</c:forEach>
};
</script>
So that it end up as valid JavaScript object (assuming that name
returns String
and age
returns Number
):
<script>
var data = {
'foo': 10,
'bar': 5,
'waa': 20
};
</script>
